Aerial Photograph Habitat Classification Purpose/Objective: To classify, delineate, and digitize boundaries for key estuarine habitats using high resolution infrared aerial photographs and spatial software (ERDAS Imagine and ESRI ArcGIS). When repeated over time, changes to estuarine habitat can be quantified. March 2010 (post restoration) December 2009 (post restoration)

Considerations for Aerial Photographs:- False color infrared or 4-band-High resolution -Taken during peak vegetation growth- Taken during low tide

Image Preparation - Masking:Create a polygon mask over your area of interest to reduce spectral variability.

Page 4: Aerial Photograph Habitat Classification

Image Preparation - Resampling (optional):Reduce class confusion by resampling high resolution imagery to a courser resolution (i.e. size of a vegetation quadrat).

1 pixel = 0.5m x 0.5m vegetation quadrat

Page 5: Aerial Photograph Habitat Classification

Unsupervised Classification (1st method):Let ERDAS Imagine group pixels in categories automatically.

Page 6: Aerial Photograph Habitat Classification

Supervised Classification (2nd method):Manually create training sites throughout the imagery for each class.

Ground -truthing:Check classifications against real ground conditions.

Classification Smoothing (optional):Reduce salt and pepper effects and improve overall appearance of your images.
